A preliminary investigation showed the senator drove off the northbound side of the road, over a culvert, up a hill and struck a mailbox with the driver side of the vehicle, the police report states. After striking the mailbox, the vehicle veered up an embankment, narrowly missing a telephone pole before getting back on the roadway.

Ingram's white 2015 Mercedes is seen on the dash-cam footage wedged into a culvert.

In the video, Ingram tells police on the scene that she was trying to turn back to go home after heading out to the grocery store.

Police are seen asking Ingram a series of questions: How is she doing? Has she been drinking? When did she crash?

Ingram appears to need assistance to stand in the road and is unable to balance on one foot when asked to complete that portion of the police field sobriety test. After the field test, the officer asks if Ingram has ever taken a blood-alcohol-content breath test and if would she be willing to take one.

She agrees.

Ingram's blood alcohol level was 0.186 percent, more than double the legal limit for driving, according to Williston Police Department records.
